META: A robot with Triangular Tracked Wheel locomotion mechanism

META is the modified version of our previous rescue robot equipped with TTW locomotion mechanism. It uses overlapped TTW configuration for faster stair climbing.

I looks cool, but I don't see the practicality of having the tread bases also act as wheels...

[amirhst]

well, it seems there is no argue about its tracks so ...

when the robot rotates its triangular frames so that they stands on their corners it's like a differential steering four wheeled robot and when it rotates its frames continuously it moves some how like a four legged robot.

I suggest having a look at my other video entitled as "AriAnA Rescue Robot Team"

Congratulation. A robot that can smack, bang ,limp and jerk it's way across a flat surface.

the tristar c0nfiguration is obviously more robust then this triangle setup.

Thanks, it is so ;-)

But honestly, I don't agree about your comparison of robustness between tri-star and triangular systems!

I should remind you that this is a tracked system while tir-stars are wheeled ones.

We've tested this robot on a 50 deg ramp so many times. It moves up, down and even rotate pretty good on that ramp where I'm sure no tri-star system has enough traction (due to the contact surface) to go up!

Hmmm. Out of curiousity, any reason you use the noisy and kinda thumpy tread system here, instead of the similarly designed Tri-Star wheel arrangement?

[amirhst]

to benefit inherent capabilities of Tracked vehicles (eg. less ground pressure, grater traction force by a given torque ...)

[tekinak007]

You dont design high end robotics with wireless to start with idiot. Adds complication and effort to the project when its not even required to be at that stage in production/testing.

Well , Nice Robot but Its Kinda heavy , :) Well i guess thats where the Triangular Wheel is used for

This rover would have no problem at all driving through a field of large jagged rocks. Good work!!

[nonbarbari]

loool funny to see 13 ppl that are jealous of robot haha... Tum up dudes, keep it up

[RockzoPhD]

Boosh!

[tekinak007]

Not to mention power needs, this way you can test without having to worry about flat batteries.

[j00d00d]

Talk about reinventing the wheel....

[xskywarpzero]

some robots have similar tread spins that climbs up and down stairs

[predben]

getting over large rocks probably
